In the Enabling step it is time to make the dream come true! In order to realize the dream, the diverse stakeholders must be able to interact with one another and have the opportunity to co-create. Platforms, whether live or virtual, facilitate and enable this interaction. They define the general rules of engagement and make data available to the stakeholders. Imagineering calls for this all to be done in a very practical way so as to enable value creation by inspiring collective creativity. You will find definitions and criteria in this chapter that are illustrated with examples. In addition, the concept of co-creation is explained. The building blocks are introduced by looking at the why and the what of the platform. We explain how to build an inspiring platform for a complex system. The chapter ends with a reminder that designing a platform is a never-ending story of curiosity, flexibility, experimentation and reflection.
